Panasonic ETD3LET40 Stepping-motor

The ET-D3LET40 is a stepping-motor telephoto zoom lens for Panasonic 3-Chip DLP projectors, covering a 4.6 to 7.4:1 throw ratio at WUXGA. It reaches large images from long distances, which suits arenas, houses of worship, and projection-mapping rigs where the projector sits far behind the audience. The stepping motor drives zoom, focus, and shift for repeatable positioning.

Focal length runs 96.6 to 154.9mm at f/2.5. The design works with 3DLP projectors excluding the PT-RQ50KU, and integrates with lens memory and edge blending. Compatible bodies include the PT-RQ35KU, PT-RZ34KU, and other 3-Chip WUXGA models.
